Eolacertilia

Eolacertilia is an extinct clade of lepidosauriform diapsid reptiles known from the Late Permian to the Late Triassic. It is uncertain as to whether they are a natural group and it has been suggested that they form a "waste basket" taxon. Currently, the only members of the group are Paliguana and Kuehneosauridae. Other genera were transferred to basal groups within Diapsida, Archosauromorpha.

Time the record covers

At most 5.2 million years on record.

The one occurrence read is dated to somewhere between 51.1 Mya and 45.9 Mya, which is a dating window rather than a span.

1 occurrence of Eolacertilia on record, most of them in the Eocene. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.

When

1 occurrences

These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

15 taxa

The Paleobiology Database records 1 site for Eolacertilia, and this reads all of them. The number is how many of those sites it was catalogued from too.

This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.

Entered from

1 reference

Each of the 1 occurrence read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. Each entry links to the Paleobiology Database's own record for the work.
